本文采用水热法合成了MnxZn1-xO晶体,水热反应条件为3mol·L-1KOH作为矿化剂,填充度为35%,温度为430℃,在Zn(OH)2中添加一定量的MnO2为前驱物,反应时间为24h.通过X射线能谱仪测量了晶体中的Mn含量,随着前驱物中MnO2含量的增加,晶体中Mn的原子百分比随着增加,Mn最大原子百分比含量超过了2%,晶体的形貌具有纯ZnO晶体的六角柱形特征.显露柱面m{1010}、锥面p{1011}、负极面O面{0001}和正极面{0001}.晶体直径为50～200μm,高度为20～100μm.
MnxZn1-xO crystal was synthesized by hydrothermal method in this work. The experimental parameters for hydrothermal synthesis were:mineralizer concentration 3mol·L-1KOH, the fill factor 35%, temperature 430℃, Zn(OH)2 doped with MnO2 used as precursor, and the reaction time 24 hours. The Mn concentration in crystal was determined by X-ray EDS. The atomic percentage of Mn in crystal increases as the concentration of MnO2 in precursor increased. The maximum atomic percentage for Mn is over 2%. The morphology shows characteristics of hexagonal prism of pure ZnO crystal. The exposed faces are hexagonal faces m{1010}, hexagonal cone faces p{1011}, negative polar faces {0001}and positive polar faces{0001}. The diameters of the crystals are 50-200μm,the heights are 20-100μm.
